GOUGH'S CAVE 1: STUDY OF PELVIS AND LOWER LIMBS

Fig. 14 Views of the Gough's Cave 1 right tibial epiphyses. Left: posterior proximal epiphysis and diaphysis. Above right: proximal medial 

 epiphysis. Below right: anterior distal epiphysis; x 0.8 (enlargement of parts of Figs 11, 12). 



index of 65.1 is just below the means of variable Mesolithic (65.4 ± 

 4.1, N = 10) and male Mesolithic (65.3 ± 4.2, N = 6) samples. 

 However, its trochlea is slightly narrower than those of most 

 Mesolithic tali, since a trochlear breadth/length index provides a 

 value of 79.1 for Gough's Cave 1, but means of 84.5 (±7.5, N = 26) 

 and 82.8 (± 6.3, N = 18) for pooled-sex and male only Mesolithic 

 samples. Finally, its neck shaft angle of 23° falls in the middles of the 

 ranges of Mesolithic (24. 1 ° ±4.4°, N = 7) and male Mesolithic (22.9° 

 ±3.5°, N = 6) samples. 



On its talo-crural articulations, it presents several variants of the 

 anterior trochlear margin (Table 18). There is a full anterior exten- 

 sion of the medial malleolar surface with an associated medial 

 extension of the trochlear margin. The lateral trochlear margin 

 likewise extends anteriorly, and abuts against a lateral squatting 

 facet, the latter matching the one on the distal tibia. 



Plantarly, the medial and anterior calcaneal facets are partially 

 fused. They exhibit a non-articular wedge extending 7.8mm in from 

 the sulcus tali, leading up to a clear fusion line 8.4mm long. In 

 addition, the posterior 8.4mm of the margin between the anterior 

 calcaneal facet and the talar head along the postero-medial portion of 

 their border is open. 



The bone lacks a clear sulcus tali facet on the anterior margin of 



the posterior calcaneal surface, but it presents rounding of that 

 surface along its more anterior sulcus tali margin. In addition, there 

 is a swelling of non-articular bone 1 4.7mm long in the antero-medial 

 portion of the postero-medial end of the sulcus tali. It is up to 4.4mm 

 wide, and it abuts against the posterior margin of the medial calca- 

 neal facet, remaining separate from the posterior facet. 



Finally, the posterior calcaneal facet has a persistent small sulcus 

 3.0mm long extending in near the posterior end of the postero-lateral 

 margin of the facet. It is the result of incomplete fusion of the 

 ossification center for the lateral posterior tubercle to the talus.
